OPERATING DEVICE FOR SPLIT WHEEL-RIMS.

Application filed July 17, 1915.

lie it known that l. l).\N,ll-ll. .l. llai'uotin. a citizen of the United States. and a resident of (random in the county oi Forest and. State of \l'isconsin have invented a certain new and useful improvement in Operating Devices for Split "hm-lllims, of which tl e following is a specification.

My present invention relates generally to split wheel rims, and more particularly to an implement or 11 *ans in connection therewith. and termin a permanent part thereof, for reducing the split rim when it is desired to release a tire therefrom, said implement and means acting, when in closed position, as a brace for supporting the free ends of the rim on opposite'sides of its gap in operative position.

\Vith these objects in mind, my invention resides in the constructions, arrangements. and operations of the rim operating tool to be new described in connection with a rim, all as shown in the accompanvinp; d rawing, forming a part of this specification, and, in whichv Figure l is a side elevation of a portion of a rim equipped with my improvement. Fig. 2- is a cross section therethrough taken substantially on line 2-2 of Fig. l, and Fig. 3 is a detail perspective view illustrating the operation oi reducing the split rim and its removal from a tire.

Referring nowto the accompanying draw-- ing, it Will. be seen that the rim 3. as shown is of conventional form,- ha ring the rounded side edges A as best seen in Fig. 2 whereby as usual to inclose the inner portion of the tire B, the rim being transversely split as indicated at i\'-"in Fig. 1 so as to permit of its reduction in circumference, and the conse quent removal oi the tire B when desired, as best seen in Fig. 3. To this end I provide an operating implement or means in the term of a U-shaped lever G, the extensions of which are pivotally connected at C and C spaced points in the length thereof, to the opposite free ends of the rim A upon opposite sides of its gap A all as clearly seen 1) reference to Figs. 1 and 2', the extensions of the lever C thus lapping the gap between Specification of Letters Yatent.

the free ends of the rim, and the cross bar .C of the lever extending across the inner of the rim as plainly seen in the same lio'ure. wln-reby in the closed position of the parts as seen in, Figs. 1 and 2/, the lever C forms an eii'eet-ive brake, eiitei'iding as it does across the inner side ot' the riin and along; opposite sides thereof across its gap, so that the rim is better held in its normal position as ind irated in l igs. l and 2, Wherein the tire is clamped in msition. Thus with the parts as shown in Figs. is simpl necessary to depress or thrust in- \vardl the outer end or erosshar G of the lever (l in order to throw one free end of the peri phery rim A inwardly and.to a position eccentric with respectto the true axis thereof. the result being to reduce the rim in circumference and permit ol the free \vitlulrau'al o'l. the tire ll as best seen by re terenec to Fig. 3.

The pivotal conneetionsll' and C may be formed in any suitable manner, but are preterabh in the nature of studs :V-irigidly connected hy brazing or other ise to the curved sides .\"ol' the rim it so as to eliminate all necessit of mutilation of the rim and adapt my improved implement to layassociated with rims now in use and obviate the neces sity of inannl'acture o'l special rims as is necessary with other implements of this nature now upon the market.

I. claim l. The combination with a split rim of an operating device including a U-shaped. ever, the extensions of which are spaced apart a distance slightly greater than the width of the rim and are pivolally connected at spaced points thereoi to the free ends of the rim upon opposite sides of its gap, and the cross bar of which lever extends transversely across the inside of the rim for the entire width of the rim and engages the latter in its closed position whereby to form a strengthening brace during the normal operation of the rim.

Z. The combination with a split rim having laterally projecting side studs at opp0 site sides of its split portion, of an operating device including a lever havingextensions which project along opposite the said sides l and 2. it

of the rim and across the gap thereof, and are pivotally connected at spaced points thereof to The said studs of the rim upon opposite sides of its gap, whereby to lap the split portions of the rim at opposite sides thereof, a part of said lever, connecting said extensions, being extended across theinner periphery of the rim.
